> Current StreamTest allows testing of a streaming Dataset generated explicitly wraps a source. This is different from the actual production code path where the source object is dynamically created through a DataSource object every time a query is started. So all the fault-tolerance testing in FileSourceSuite and FileSourceStressSuite is not really testing the actual code path as they are just reusing the FileStreamSource object.
> Instead of maintaining a mapping of source --> expected offset in StreamTest (which requires reuse of source object), it should maintain a mapping of source index --> offset, so that it is independent of the source object.
